Cell Tower Structural Analysis for Co-Location
Cell Tower Structural Analysis for Co-Location
(OP)
I am looking for some background information related to which standard should be used when performing a structural analysis of an existing cell tower where additional equipment is to be added to it. I have found the TIA/EIA-222-F standard and a new revision TIA/EIA-222-G that was published in 2006. Revision G increases wind and ice loading. Which should be used and who determines which guidelines to use. Is it state, federal, local or industry regulated.
Thanks
Thanks

Check with your client for which version of code F or G he wants you to use. For example, Crown Castle International requires their towers are analyzed accordance with G-code. Also, check with the local code enforcement department where the tower is located. The industry uses G-code now.

If this is a guyed tower, analysis for this type of structure is fairly complex. Make sure you have the proper engine (ie GuyMast or ERI software) to do the analysis.

As for which one to use it would seem appropriate to use Rev. G, however we have noticed that several towers built prior to 2006 were very close to their design limits using Rev. G and no room for additional loading. This would then require the owner to modify or reinforce the tower if they plan to install additional antennas/etc. to comply with Rev. G.
Our company uses RISATOWER which formally was ERITOWER. The original author of ERITOWER has since passed several years ago and [RISA] has taken over the software now called RISATOWER (from what we undertand). We have tried other programs (guymast) but have found RISATOWER to be the most appropriate program for our field.
So to answer your question - Use Rev. G.
